Unit Circle T Shirt
I created a T Shirt with the 16 point Unit Circle on front and some numbers of the back to help remember the cosine and sine coordinates of the 5 points on the first quadrant of the Unit Circle. Most of the video time is in explaining how the 5 numbers, 04, 13, 22, 31, and 40 relate to these 5 points in quadrant one.
